摘要
用XPS角分布法研究了铌和钽在室温下与干燥空气的相互作用.结果表明铌和钽表面生成了化学组成分别为Nb_2O_5和Ta_2O_5的氧化物,氧化膜内金属原子和氧原子呈混合状态,从而排除了这种相互作用仅仅是化学吸附的可能性.
XPS angular distribution has been used to study the interaction of dry air with Nb and Ta metals at room temperature. The results show that Nb2O5 and Ta2O5 are formed on the surface of metallic Nb and Ta respectively. The metal ions are mixed with oxygen ions within the oxide film, which rules out the possibility of the interaction being oxygen chcmisorption only.
